Nitrate: Satlantic. ISUS. (CP01CNSM-00004)

The ISUS is a sensor used to measure concentrations of dissolved chemicals directly from their Ultraviolet Absorption Spectrum. It is a real time, chemical free sensor designed to overcome the traditional challenges associated with reagent-based nitrate analysis in aquatic environments.Nitrate sensors optically measure the amount of nitrate (NO3-) dissolved in seawater by examining its absorption of ultraviolet (UV) light. The optical sensor provides fast response measurements, allowing for the sensor to be deployed on profilers, gliders, and AUVs. Location: 40.1332, -70.7784; Near Surface Instrument Frame.
